For anyone concerned about the cost of the platinum membership AND you are in the domain business:
You probably will be able write the cost off, since being a member is almost a foregone conclusion if you want to stay in business.
Note to GregR. You might think about having Corporate Accounts someday. I'm sure all the heavyweights will be trying to hook up with you if they haven't already. A corporate account could be one higher than "plantinum" and would involve cheaper domains/services etc through listed "partners".
Also any interest in setting up a affiliate network selling DNF memberships??? Just a thought. It might be more of a headache then it's worth, but a quick cost analysis may help you decide.
